• Fix plugin/theme conflicts, PHP and JS errors, and database issues.

2. Performance & Core Web Vitals

• Manage DNS, SSL, Cloudflare (WAF, rate limiting, bot rules), redirects and migrations.
• Handle malware, XSS/SQLi/CSRF prevention, user permissions and backups.

• Linux, SSH, Git, Nginx/Apache, Cloudflare, and Redis/object caching.

  you use AI coding tools efficiently, but you review every change yourself. Nothing goes live without a human check for security holes and broken functionality.
• Not suitable: candidates who only install themes and plugins, or who ship AI-generated code unreviewed.

• High-traffic publishing or news sites; EDD/WooCommerce; membership sites.
• Large WordPress databases, Google Ad Manager, Firebase, multi-site setups.
